The cover 200 includes first and second covers 220.

The first cover 210 may be formed to cover most of the rear surface of the main body 103. The first cover 210 may be disposed to cover one end of the main body 103. For example, the first cover 210 may extend from the rear surface of the main body 103 toward one end thereof.

The first cover 210 may have a through hole in the corresponding region so that the camera 121 'and the sound output unit 152' mounted on the rear surface of the main body 103 may be exposed to the outside .

The first cover 210 may include first and second regions 211 and 212. Referring to FIG. 5 with reference to FIG. 4, a first region 211 is formed to cover a battery 191 accommodated in the main body 103. The second area 212 is a part of the main body 103 of the wireless communication unit 100 (the broadcast receiving module 111, the wireless Internet module 113, the short distance communication module 114, and the location information module 115) As shown in FIG.

The first and second regions 211 and 212 may be made of different materials. For example, the first region 211 may be formed of a conductor, and the second region 212 may be formed of a non-conductive material so that electromagnetic waves can be transmitted and received.

In this figure, the first region 211 is formed of aluminum and the second region 212 is formed of PC (PolyCarbonate). The first cover 210 can be manufactured by PC injection molding of aluminum. According to the above structure, the wireless communication unit 110 may not be influenced by the first cover 210 in transmission / reception.

The first cover 210 may be formed with an auxiliary wireless communication unit 117 having a frequency band different from that of the wireless communication unit 110 installed in the main body 103. Referring to FIG. 2, an auxiliary antenna 117a electrically connected to the main body 103 is disposed in the second area 212. As shown in FIG. The auxiliary antenna 117a may be, for example, an antenna for wireless communication with mobile payment means.

The first cover 210 may be provided with a connection terminal 117b for electrically connecting the auxiliary antenna 117a to the printed circuit board mounted on the main body 103. [

The second cover 220 may be formed to cover the remaining portion of the rear surface of the main body 103, which is not covered with the first cover 210. The first cover 210 may extend from the rear surface of the main body 103 toward the other end so as to cover the other end of the main body 103.

The second cover 220 is slidably coupled to the first cover 210 and is detachably attached to the main body 103. For example, the first cover 210 is provided with a through hole 213 (see FIG. 8) penetrating therethrough in the thickness direction, and the second cover 220 is arranged to cover the through hole 213. The first and second covers 220 are coupled to the main body 103 when the second cover 220 is slid with respect to the first cover 210 to completely cover the through hole 213. [

When the second cover 220 is slid with respect to the first cover 210 in a state where the cover 200 is coupled to the main body 103, the engagement of the second cover 220 and the main body 103 is released. The sliding portion 230 that enables such a mechanism will be described in more detail with reference to FIG.

6 is an enlarged view of the sliding portion 230 shown in FIG.

Referring to FIG. 6, the sliding portion 230 is formed such that the second cover 220 is slidable with respect to the first cover 210, and engages the first and second covers 220. The sliding portion 230 includes a guide groove 231, a rib 232, and a guide member 233.

The guide groove 231 is formed along the sliding direction on both sides of the first cover 210 and guides the sliding of the second cover 220. As shown in the figure, the guide groove 231 may be formed to be recessed from the recessed inner surface of the cover 200 toward the outer surface. The guide groove 231 may be formed in an arc shape so that the second cover 220 can be simultaneously slid and tilted relative to the first cover 210.

The ribs 232 are formed to protrude from the second cover 220 and are arranged parallel to both sides of the first cover 210. The ribs 232 may be slidable on the inner surface of the cover 200.

The guide groove 231 may be recessed in two stages so that the rib 232 and the guide member 233 are inserted. According to the above structure, since the ribs 232 are inserted into the guide grooves 231, no step is formed on the inner surface of the cover 200, so that a simple structure can be obtained.

The guide member 233 is formed to protrude from the rib 232 and is slidably coupled to the guide groove 231. For example, the guide member 233 is formed to protrude toward the guide groove 231 on the surface of the rib 232 facing the first cover 210.

The guide member 233 can be rotatably formed in the guide groove 231 so that the second cover 220 can be tilted with respect to the first cover 210. The guide member 233 may have a circular or spherical shape and may be formed to have a point contact or a line contact with the surface forming the guide groove 231. According to the structure, the second cover 220 has an advantage that smooth sliding and tilting with respect to the first cover 210 is possible.

Alternatively, the guide groove 231 may be formed in an arc shape so that the second cover 220 may be slid and tilted simultaneously with respect to the first cover 210, as described above.

The ribs 232 may be formed to press the main body 103 when the second cover 220 is tilted with respect to the first cover 210. One end 232a of the rib 232 protrudes from the cover 200 or a length from the one end 232a to the center of rotation of the guide member 233 is larger than the length from the main body 103 May be longer than the length of the guide member 233 to the rotation center.

A stopper may be formed on the first cover 210 to restrict rotation of the second cover 220 by more than a predetermined angle when the first cover 210 is tilted with respect to the first cover 210. The stopper may be formed to protrude from one surface of the first cover 210, for example. In this case, when the rib 232 is rotated over a certain angle, it is caught by the stopper, so that the degree to which the second cover 220 is tilted with respect to the first cover 210 can be adjusted.

The second cover 220 may be configured to automatically tilt relative to the first cover 210. For example, the cover 200 or the main body 103 may be equipped with an elastic member 140, which is configured to press the ribs 232 when the ribs 232 slide over a predetermined length. The second cover 220 is simultaneously slid and tilted so that a space is formed between the main body 103 and the second cover 220 so that the cover 200 can be easily separated.

Referring to FIG. 6 with reference to FIGS. 4 and 5, the second cover 220 covers the mobile communication module 112 mounted on one end of the main body 103, for example, . The second cover 220 may be made of a different material from the first cover 210, specifically, the second region 212 of the first cover 210. For example, the second cover 220 may be formed of a nonconductor so that a radio signal can be transmitted and received, and the second region 212 may be formed of a conductor.

The rib 232 and the guide member 233 are frequently brought into contact with the first cover 210 and the main body 103 when sliding and tilting so that they can be formed of materials having durability and wear resistance. For example, a rib 232 and a guide member 233 formed of stainless steel (STS) may be integrally formed by injection molding on the second cover 220 formed by a PC. According to the above structure, the second cover 220 can have strong durability against frequent sliding and tilting without affecting the wireless communication unit 110 in transmitting and receiving.

7 and 8 are exploded perspective views showing a coupling structure of the main body 103 and the cover 200 shown in FIG.

Referring to FIGS. 7 and 8, the main body 103 and the cover 200 are formed with locking portions for locking or unlocking the main body 103 and the cover 200, respectively. The locking portion includes first and second locking portions (250, 260). The first and second locking parts 250 and 260 may be formed so that the first and second covers 220 can be engaged with one end and the other end of the main body 103, respectively.

The first locking part 250 may include a groove 251 and a hook 252 formed to allow the first cover 210 to be hooked on one end of the main body 103. For example, a groove 251 is formed at one end of the main body 103 and a hook 252 is formed at one end of the first cover 210 so as to be fitted into the groove 251, The first cover 103 and the first cover 210 can be locked.

The second locking portion 260 may include a locking groove 261, a locking hole 262, and a locking hook 263 that allow the second cover 220 to be engaged with the other end of the main body 103 . Specifically, the main body 103 has a latching groove 261 formed at the other end thereof, and the latching hole 262 may be formed at the other end of the first cover 210. The other end of the second cover 220 is formed with a hook 263 protruding through the coupling hole 262 to be fitted into the coupling groove 261 so that the second cover 220 is inserted into the first cover 210 The main body 103 and the second cover 220 can be locked.

The hook 252 and the hook 263 may be formed with protrusions protruding from at least one side so as to be fixed to the groove 251 and the engaging groove 261, respectively. Receiving grooves are formed on at least one surface of the groove 251 and the engaging groove 261 so that the hook 252 and the engaging hook 263 are inserted into the receiving groove.
